As much as I like to see a lady's face before I book with her, I totally get why most women blur their faces. Some SPs I've seen have shared with me their stories of harassment when people outside of this community recognize them in public. The world in general doesn't understand or accept this industry yet, so until that changes women will need to exercise some discretion when advertising their services.
Nondeju - if you don't like a ladies' ad, then don't use their services. If she looks older than advertised and you're not into it when you show up, then walk. You're kind of coming across a bit unhinged here, dude.
